Infiitely many.

Start with integers and addition/subtraction:

6+5, 7+4, 8+3, 9+2, 10+1, 11+0, 12-1, 13-2, ...

Then with one decimal place:

5.5+5.5, 5.6+5.4, 5.7+5.3, and so on.

Then with 2 dp, 3 dp, and so on to infiitely many dp.

Next look at multiplication/division.

1*11, 2*5.5, 3*3.66..., 4*2.75, and so on

Then there are other ways of combining numbers, such as exponentiation and so on. But the solar system will have ended before you get there!
